But Jenner's most recent update has sparked outrage among fans, critics, and fellow parents alike. A photo and video posted on Jenner's Snapchat reveal that the 5-month-old apparently has her ears pierced.

"Does a baby need to have her ears pierced because she thinks it looks good and is fashionable? I just don't think it's OK," one person commented on a post from a fan account. "Is she going to start putting big earrings in her [ears] now [they're] pierced? A [baby's] ear is still forming and growing at that age."

"Piercing a babies ears!!!! @kyliejenner be ashamed of yourself. This is utterly disgraceful," one person wrote.

Many commenters asserted that their concern has nothing to do with a disdain for Jenner herself, but is rather due to their own experiences as parents. Indeed, Jenner's half-sister Khloe Kardashian ignited similar reactions when she recently revealed her 2-month-old daughter True also has her ear pierced.

The AAP does recommend parents "postpone the piercing until your child is mature enough to take care of the pierced site herself," but also notes, "if the piercing is performed carefully and cared for conscientiously, there is little risk, no matter what the age of the child."

"For Latina moms, piercing their baby girls' ears has nothing to do with vanity. It's simply a cultural tradition," Roxana Soto, co-founder of Spanglish Baby, has said, according to a report by TODAY. "I honestly don't understand why some people care and why some moms have made such a big deal of piercing baby's ears ... I don't care what others think. Because we're talking about my daughter and about something completely harmless that is completely normal in my culture."

While Jenner presumably did not pierce Stormi's ears for cultural or religious reasons, it does seem safe to assume that she has the resources to access the best doctors and pediatricians, none of whom would let a mom perform an unsafe procedure on a baby.
